One study found that many young men showed an increase in aggressive behavior a few hours after eating a diet:

Question

Quizplus · Accepted Answer

The study found an increase in aggressive behavior after a diet low in tryptophan and high in phenylalanine. Tryptophan is an amino acid precursor to serotonin, a neurotransmitter that regulates mood and behavior. Low levels of tryptophan are known to decrease serotonin levels, which can result in more impulsive and aggressive behavior. Phenylalanine, on the other hand, is a precursor to dopamine, a neurotransmitter that can stimulate aggression if levels are too high. Therefore, a diet low in tryptophan and high in phenylalanine can lead to increased aggression. Options A, B, and D do not explain the study's findings.
